Claim 1
Independent Claim
187 words
A ski bike comprising: a frame including a generally horizontal tubular top member, a generally vertical tubular front member connected to the forward end of said top member and extending downwardly with respect to said top member, a generally vertical tubular rear member connected to the rear end of said top member and extending downwardly with respect to said top member, and an inclined tubular member connected to the rear end of said top member and to the lower end of said front member; a seat mounted on the rear end of said top member; a rear ski having its forward end curved upwardly and connected to the junction of said inclined member and front member; shock absorber means connected to the lower end of said rear member and to said rear ski and interposed therebetween; a further generally vertical front tubular member connected to said first named front member and extending essentially parallel thereto for rotation about a generally vertical axis; handlebars connected to the upper end of said further front member; and a front ski connected to the lower end of said further front member.
